1. is attributable to a mental or physical impairment or combination of mental or physical impairments;
2. is manifested before the person attains age twenty-two;
3. is likely to continue indefinitely;
4. results in substantial functional limitations in three or more of the following areas of major life activity:

A) self-care,
B) receptive and expressive language,
C) learning,
D) mobility,
